Researchers have found that houseflies carry hundred of harmful bacteria than previously known and spread deadly diseases in humans. Though scientists have suspected long back that bacteria played a key role in spreading and carrying diseases as they live close to humans. This study added further proof of that threat and it has been published in the Journal Scientific Reports.

Professor at Pennsylvania State University in the US, Donald Bryant said,”We believe that this may show a mechanism for pathogen transmission that has been overlooked by public health officials, and flies may contribute to the rapid transmission of pathogens in outbreak situations.”

From three different continents, the researchers have examined microbiomes of 116 blowflies and houseflies. After the examination, they found that these flies carried hundreds of different species of bacterias and few of them are very harmful to humans. According to the study, houseflies and blowflies share over fifty percent of their microbiome, a few acquired from the environments they inhabit and a mixture of host-related microorganisms. And flies collected from urban environments carry more pathogens than the flies collected from stables.

Both carrion fly species, blowflies and houseflies – often exhibit filthy matter because they use decaying organic matter and faeces to nurture their young ones.

From the blowfly samples collected in Brazil, the researchers found 15 instances of the Helicobacter pylori, a pathogen often causing ulcers in the human gut. However, flies may not be all harmful. But they could turn into helpers from human society and it can even act as an early-warning system for diseases according to the researchers.

Stephan Schuster from Nanyang Technological University, Singapore stated, “The legs and wings show the highest microbial diversity in the fly body, suggesting that bacteria use the flies as airborne shuttles.”
